Abstract: Using the coal mine water filling factors analysis method and hydrogeological analogy method to research the coal mine flooding of Gong County, the analytical results show that the sandstone fissure water in the coal seam roof, which through mined-out water flowing fracture zone into tunnel,is the main source of water flooding,and the goaf water flow fractured zone is the main water channel. The water inflow is predicted by hydrologic geology analogy method,3 763. 2 m3/d of normal inflow and 7 051. 2 m3/d of maximum inflow in Matangcun coal;and 547. 2 m3/d of normal inflow and 864. 0 m3/d of maximum inflow in Gaoshi coal. According to the flooding characteristics of Matangcun coal mine,the prevention and control counter-measures aiming at flooding have proposed,and theoretical data for mine water prevention and control work have provided.
